My friends daughter who is divorced got an alliance from a boy who is also divorced. He has informed her that his entire family, father, mother and sister are thyroid prone. In this context whether they can go for an alliance with that person. Some one told that sexual life will be disturbed after sometime due to thyroid. Please guide her to take decision. Whether children will also suffer from thyroid as hereditary. Whether she can lead happy sexual life. She is 33 and he 38.
